One slight correction, Aikido is based off a clan art, Totome Ryu Jujitsu (I believe that was the name of their art) and revolves around eight techniques that clan created and perfected, it's relationship with any other form of Jujitsu is distant at best.

But you are totally wrong, that is not Judo. And if you have done judo for ''10 years'' you would of been able to see that. The guy doing the shoulder lock called ''omoplata'' is Clark Gracie, a brazilian Jiu Jitsu black belt. This was during the pan ams this weekend.
And the guy you see in the background is not going for a leg lock, he is going for an armbar from backmount

Yes, actually people who do these sports/martial arts care. It's the same concept as people who are from Denmark are called Norwegian or Swedish, that gets them pissed off. Or let's take a video game example. CALL OF DUTY IS THE SAME THING AS BATTLEFIELD. There you go. Now please take your rage somewhere else.
